1) The document studies the use of marble powder as a partial replacement for cement in normal compacting concrete. 2) Five concrete mixes were tested with 0%, 5%, 10%, 15%, and 20% replacement of cement with marble powder to determine compressive, split tensile, and flexural strengths at 7, 28, and 56 days. 3) The results showed that compressive, split tensile, and flexural strengths generally increased up to 10% replacement of cement with marble powder compared to the normal mix without replacement. Higher replacements of 15% and 20% typically showed reduced strengths compared to the 10% replacement mix.
